Latest Patents
One of Hanxi Chen's latest patents is titled "Efficient Device Debug System." This invention provides a method and system for electrical testing of an integrated semiconductor substrate that has at least two signal processing layers. The substrate can be protected by a layer of materials such as plastic, silicon, silicon oxide, or silicon nitride. The method involves exposing a selected region of one substrate layer by etching or forming a controllably small aperture in the overlying layers to access at least one circuit trace. A selected electrical signal is then applied to the trace. Additionally, a second aperture can be formed to expose another circuit trace, allowing for the testing of signal propagation in the substrate circuits. The shapes of the apertures can vary, including linear or curvilinear polygons.
Another significant patent by Hanxi Chen is "Efficient Debug Package Design."
